Read the mind of your pet monkey

Brain implants have been used to read the minds of monkeys to predict what they are about to do and even how enthusiastic they are about doing it. This is the first time such high-level cognitive brain signals have been decoded, and the research could ultimately lead to more natural thought-activated prosthetic devices for people, such as a robotic arm that is triggered by thought.
